For more than just that, no?  `C-x 5 C-x C-f' is not as simple as
`C-x 5 f'.  Occam would grumble.

Yes, Occam might be somewhat happy to eliminate the "extra" commands
`*-other-window' and `*-other-frame', and just have `*'.  But the devil
is in the details.  It's not clear, so far, whether users would find
this simpler or more complicated.

Do you mean only for `C-x 5 f'?  Someone will likely want to bind such
a command (or whatever it becomes) to additional keys, no?  Sure s?he
could make do with a lambda expression or whatever, if necessary.
But why?  (It's not clear to me just what you have in mind.)

For more than just that, I expect...

BTW, what do you do with `C-x 4 C-x 5 C-x C-f'?  By your description,
I guess that does the same thing as `C-x 4 f'?

Suppose it were `C-x 6', for kicks.  Would `C-x 6 C-x 4 C-x 5 C-x C-f'
then be the same as `C-x C-f'?

Will you at least be keeping `C-x C-f' "for backward compatibility"?

Could we see a spec of some kind (better description), before the
implementation and possible deprecations?
